SPECIFICATION forming part of Letters Patent No. 633,1 52, datedSeptember 19, 1899.

' Application filed A ri15, 1899. Eerial No.7l1,825. (No model.)

To all whom it may concern:

Be it known that I, EDWARD L. PERRY, a citizen of the United States,residing at Paterson, in the county of Passaic and State of New Jersey,have invented certain new and useful Improvements in Composite Jacketsfor Printers Inking-Rollers; and I do hereby declare that the followingis a full, clear, and exact description of the same, reference being hadto the annexed drawings, making a part of this specification,'and to theletters of reference marked thereon.

The object of the present invention is to provide means whereby theordinary printers inking-roller that becomes worn out and useless may berenewed by utilizing the old roller as a body and giving to the same anew inking-surface.

The invention therefore consists in providing a jacket comprising acomposite hollow cylinder of solid elastic material adapted to slip overand fit the old body of the inkingroller and held thereon by its owninherent elastic qualities, whereby a new inking-surface is providedthat will possess all the necessary requirements of a perfectinking-roller.

Figure 1 of the drawings is a side elevation of an inking-rollerembodying my invention; Fig. 2, a cross-section thereof on an enlargedscale, Fig. 3, a detail perspective view showing a portion of theelastic composite jacket.

In the accompanying drawings, A repre sents the elastic jacket, and Bthe ordinary printers inking-roller which forms the body to the jacketwhen said jacket is fitted over the same. The roller B is of the usualcomposition from which printers inking-rollers are formed, such as glueand molasses or other composition. The jacket A is of an elasticmaterialand composed, preferably, of

crude india-rubber, twenty-eight parts; whiting, fifty-nine parts; drylead, eleven parts; sulfur, two parts, and add to this from twenty-oneto forty-two parts of corn-oil, which compound is formed and molded intothe desired shape and subjected to either a steam or dry heat of therequired degree until properly vulcanized.

I do not desire to limit myself to the compositionabove described, asany composition that will give to the jacket the required elasticity tohold itself upon the roller and possess the required surface to take upand distribute the ink perfectly will serve the purpose intended.

It is the main purpose of this invention to provide an article completein itself that can be placed upon the market within the reach ofprinters and others requiring the same whereby the old and worn-outrollers that have been cast aside can be utilized by providing the samewith an entirely new inkingsurface, this being attained by the compositeelastic jacket A, which is slipped over the old inking-roller and thejacket held thereon by its own inherent elastic qualities.

Should the surface of the jacket become worn and useless, it may beremoved and replaced by a new one, thereby using the old rollerindefinitely as a body or core to the jacket.

The jacket, it should be understood, is

formed of solid elastic material in contradistinction to the old andordinary covering of leather or rubberfaced cloth, and consequentlyholds itself in place upon the body of the roller by its own inherentelasticity without the necessity of additional fastenings.

These composite jackets may be made of various lengths and of anydesired diameter and thickness to adapt them to any size inking-roller,or the surface of the old and wornout roller may be first trimmed in alathe to adapt the roller to the diameter of the jacket.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

As an article of manufacture, a composite jacket for renewing thesurface of printers inking-rollers, said jacketconsisting of a hollowcylinder of solid elastic material, where by the same may be held inplace upon the roller by its own inherent elasticity, substantially asand for the purpose set forth.

In testimony thatI claim the above I have hereunto subscribed my name inthe presence of two witnesses.
